MIACHINE FOR MAKING BRICKS, TILES, AND OTHER BUILDING MATERIALS. I

Application led August 29,1921. Sera1fNof49604.

To all whom t may concern.: Be it known that I, GEORGES-V. PICOT, a citizen .of the Republic of Switzerland, and a resident of Paris, France, have invented a new and useful lmprovedlvlachine for Making Bricks, Tiles, and Other Building Materials, which improvements are fully set orth in the following specification.

This invention relates to the manufacture lo of hollow bricks, tiles and other building materials by double compression, and has for its object to provide an improved apparatus for this purpose.

According to the invention the apparatus la comprises brielystated a reciprocating plate carrying the double compression members which are adapted tooperate in one of three moulds carried, upon a rotatable member disposed above the reciprocating plate and 2o arranged so that a. 'charged mould maybe brought into line with. the compressor at each reciprocation of the latter, one of the moulds being discharged and another lilled i Whilst the third is Operated` upon by the pressing members.

In order that the invention may be readily understood, reference willnow be made to thel accompanying drawings in which Figure 1 is a vertical section of the apparatus taken on the line1-1 of Figure 3;

' Figure 2 is a section on the line 2--2 of Figure 3.

Figure 3 is a plan view of the apparatus; Figure 4 is a top plan view of the compression plate;

Figure 5 is a section on the line 5-5015 Figure 4, and, Y y

Figure 6 is a diagrammatic view showing the methodofdischarging the finished brick. `.As shown in the drawings, the apparatus comprises a base 1 of cast iron or other metal within which is disposeda train of gears.

These gears are carried between depending' parallel partition walls 2 formed integralwith the casting 1 and strengthened by webs 3. Two connecting rods 4 passing ythrough openings 5 in the base 1 actuate a reciprocating press plate or cross-head 6 mounted to slide on two'uprights 7l and a` spindle 8. A collar 9secured upon the spindle 8 supports p a member- 10 comprising three similar lmoulds a, c, said member being rotatably` mounted on lthe spindle 8. VThe rotary movement of the mould carrier 10 may be ettected either by hand or automatically by means of a motor (not shown); and at each operation thereof, whether man-` ual or automatic, it is turned through 120, or one-third of la revolution, in order to bring the moulds in propercalinement with the compressing, expelling and other de,-v

vices cooperative therewith. The carrier may be locked in position by any suitable means (not shown). 4 y

The two uprights 7. and the spindle Spare secured together by the plate 11 against which the material in the mould shown at a in the drawing is compressed whilst the brick which has previously been compressed in the mould I; is expelled by a plunger 12 secured to the plate 6 at d or to the mould b.

The mould shown in the drawingsl at c is in position for charging., Before putting the material into the mould, the 3 mm. sheet iron plate 14 and the cast iron plate lare caused to slide one over the other through a slot formed in the lower part of the mould. When the mould contains the necessary quantity vof material, this latter is covered by a plate 16 of 3 mm. sheet iron. r

The plates 14, l5, 16 are perforated to accommodate solid or hollow cores 17 securely fixed to the plate 6. These cores pass freely through the perforations in the plates 14, 15, 16 during the pressing operation and thus serve to form the openings in the hollow brick or tile aswell as .to eiect compression ot the material.

As the material used for making the brick is slightly damp it does not :tall through the openings formed by these perforations while the moulds are being rotated. lhen the plate 6 moves down and withdraws `the cores 17, the dogs 18, which are lodged in each mould, retain the plate 15.

'To facilitate the removal of the brick 13, a table 19 of strong, polished sheet ironis fixed at a distance from themould and at a. convenient height.l When the plunger 12 is at the end of its upward stroke the moulded brick or block and plates 14 and 15, which have been ejected from the mould bythe movement of the plunger, are slid across the top of the mould until the plate 15 is stopped by its Contact with the edge of table 19 (Fig. 6). YThe brick continues its movement and slides over the plate 15 until it reaches the opening 20 where it can be easily removed;

The plate 15 will remain upon the plunger and can be used again for the next oploo ' the filled mould.

eration, the plate 14 remains for a day beneath the brick in the drying oven and the plate 16 is removed as soon as the brick is in position. 'The operation is as follows, assuming that the mould t is in compressing position, indicated at X (Fig. 3) ,the mould b in ejecting position at Y; and the mould o in charging position at Z. Starting with the empty mould c, the two plates 14 and 15 are slid into the bottom of the mould and the latter is then filled in some suitable manner, by hand or otherwise (the `precise method forming no part of the invent-ion), with the material to be moulded, after which the cover plate 16 is put in place on top of The carrier 10 is then movedl through one-third of a revolution, either manually or by means of a motor, thus bringinor mould G into corresponding position at mould a into ejecting position at Y and mouldb into lilling position at Z. Mould c is thereupon subjected to a compressing action, for the rods Ll, after having released the preceding mould, descend and ascend during the partial revolution of carrier 10, and in their upward movement raise the cross-head 6 with them, during which time the cores 17 pass through the perforations in the plates let and 15 into the interior of the mould and linally through the perforations in the top plate 16 and in the tie plate 11. As the upward movement of the cross-head continues, the plates le and 15, which rest upon the shoulders at the base of the cores, are forced into the mould and, in consequence, subject the material therein to a vertical compression; and it is to be observed that the upper portions of the cores are made conical (Fig. l) the purpose being to enable said portions to exert some pressure laterally against the material, so that during the working stroke of the cores there is, in effect, a double compression, so to say, viz: a vertical compression produced by the vertical movement of the plates 14 and 15 and a lateral compression produced by the special shape of the cores. It will also be observed that the moulds, or mould cavities, in the carrier 10 are open at both top and'bottom; and that the plates let and 15 are utilized to close their bottoms, and the plates 16 to close their tops, the tie plate 11 being disposed immediately above the mould when the latter reaches the compressing Vposition X so as to form a rigid support or backing against which the plate 16 and the material to be moulded are forced by the action of the cross-head and the cores.

At the completion of the compressing step, as above described, the cross-head moves down, carrying the cores with it and withdrawing them from the mould. The carrier is then again turned through vone-third of a revolution, thus moving the mould into position Y where the moulded block 13 is ejected from the mould by the action of the plunger 12 which raises it out of the mould together with the plates 14, 15 and 16, as already explained, thus completing the sequence of operations. It will be understood, however, that while the mould c is passing through this cycle, the other two moulds a and are going through the same treatments, but timed, respectivel one and two stages ahead of those of mou d c; thus, while mould c is being charged, the material in mould a is being compressed, and the moulded block in mould b is being ejected therefrom; whereas when mould c has moved to position X, the block in mould d is being ejected, and mould is being lled, and when mould 0 has moved to the ejectinr station Y, mould a is being filled and moult Z9 is undergoing` the compression step.

It is to be understood that the arrangement described may be modiiied, as for in-` stance by making the brick pass out below the mould instead of being raised above it.

I claim 1. In a hollow-block machine, the combination of compression mechanism embodying a pair of vertical guides, a vertically-reciprocating cross-head slidably connected at opposite ends therewith and provided with a vertical core, and a tie-plate connecting the upper ends of the guides and having a slot conforming to the size and shape of the core and disposed directly in line therewith; and a mould carrier disposed between the crosshead and the tie-plate and having a plurality of moulds at top and bottom, said carrier being movable relatively to the crosshead to bring the moulds successively into position directly in line with said core and tie-plate, thereby to enable the core to move into and through the material in the mould thereover and into the slot in the tie-plate during the upward movement of the crosshead, and the tie-plate to close the upper end of that mould at such time.
